How to Install/Unroot Galaxy Nexus GSM to Android 4.0.4 OTA! [IMM76I]

Posted onApril 25, 2012byMax Lee

For those of you who want to install the latest Android 4.0.4 OTA IMM76I update from Google, the latest stock ROM, here’s how to do it. Also, this is an unroot method back to stock. It will erase all your personal settings and apps so, be sure to make a backup of your ROM, backup your apps using Titanium backup app, and also make sure to backup SMS text messages (if needed) using SMS Text Backup app.

*Note – This is ONLY for Galaxy Nexus GSM, not for Verizon/Sprint versions.

Step 1. Take the battery out and put it back in. Then hold down Volume Up, Volume Down, and Power button together until you enter the fastboot mode.

Step 3. Under Device Manager, make sure you have something like “Samsung Android ADB Interface”. If you don’t, manually update the drivers. If you have trouble, watch the video as I walk you through this part in the vid. (Download drivers here) For Mac and Linux, you don’t need drivers, skip this step.

You will need a rooted Galaxy Nexus to install all ROM/kernels.NOTE: PLEASE ONLY INSTALL ROMS INTENDED FOR YOUR VERSION OF GALAXY Nexus! Otherwise you WILL BRICK YOUR PHONE and I will not be responsible!How to Root GalaxyNexus!

Is this method will work for the US “takju” galaxy Nexus (currently available on the Google Play store for US customers)? I am asking this because your model seems to the International version AKA “yakju” Galaxy Nexus.

Hey why can’t I just flash the galaxynexusunroot404 with cwm.. I’m having trouble with my drivers.. I keep trying to install them on my xp comp and they just dont show up when i try to update adnroid1.0.. What am i doing wrong i tried everything to get samsung drivers to work on this pc.. again i have xp im pretty sure that has a big part with my problem..

I followed this guide one step at a time, didn’t miss a step, didn’t receive any error (other than those shown in the guide). Everything went on as it should, I guess.

I have a Google Galaxy Nexus phone, Android 4.0.2, Maguro.
I used my windows 8 Consumer Preview and the built in Command Prompt.

After this installation, which I think went trough without any error, the Google-logo was shown (I think), the usual colorful video was played, then it stopped on the last frame. The animation was almost completely faded and was frozen for a while, then it turned black. A small vibrate, then the Google-logo is show for a while, the screen turns black again and it vibrates again and shows the Google-logo yet again (hinting on a restart) and it continues on like that.

I have taken out the battery (and put it back) and started the phone. Vibrate, logo, vibrate, logo… I have read that someone else has gotten this error and didn’t get any help either. Don’t know how usual this error appears but someone maybe recognize it and know how to fix it? Would be great to have my phone working again.

Okay, I don’t know what I did, but my phone works now again. I started it just for random, and maybe in rage that it won’t work, and it did vibrate, logo and continued… showed the color-video… vibrated, logo and video and then the welcome screen. Don’t ask how I did it, I don’t know what I did, but my phone works now.
I was a bit sacred that my phone was broken/bricked but I have only myself to blame, I did follow this guide, no one forced me to do it, but it works now.

okay but it is a nexus GSM version gt i9250.
i really want to update root and use the wifi tether with your method 🙁
Sorry i never flashed an android before.
what can go wrong if i use this method with the NTT-Docomo SC-04D Nexus.
it uses a normal sim card.

Hi I tried using your guide to unroot my galaxy nexus to flash back to the original stock in an attempt to get Jellybean as all previous attempts to flash it failed. It also wasnt updating properly, and would show the green android with a red exclamation mark on reboot.

When I went into command prompt to flash the maguro-promela03.img it would say and just hang there forever.

I reinstalled the samsung driver you provided just in case mine was out of date and now the driver shows unknown device when I open up bootloader. When I turn my phone on normally it shows under device manager like it should and shows the Samsung Android ADB Interface… what am I doing wrong when I put on boatloader??

I have used this process before with no problems, yet this time when I get to “./fastboot-mac. flash bootloader bootloader-maguro-primela03.img” it says no such file or directory. Yet this file is indeed in the galaxynexusunroot404 folder in “downloads”. Any ideas as to why this might be happening?
